Psychological and Physiological Moderators of Perceived Exertion in Aerobics

126 young adults (18–35 years; 63 females, 63 males) completed three step-aerobics sessions at light, moderate, and vigorous intensities. Xiaoxue Gao collected 1,134 repeated observations of heart rate and perceived exertion alongside baseline anthropometric, physiological, and psychological assessments. The dataset was last updated on May 7, 2026.

Use Cases

• Modeling the coupling between heart rate reserve and perceived exertion based on repeated observations across three intensity levels.
• Testing moderation effects of physiological status (e.g., cardiorespiratory fitness) on the perceived exertion slope.
• Exploring the association between psychological traits (e.g., interoceptive sensibility, exercise self-efficacy) and perceived exertion.
• Investigating potential perceptual ceiling effects during vigorous exercise based on Borg scale ratings.

Strengths

• Includes 1,134 repeated observations from 126 participants, providing a substantial sample for repeated-measures analysis.
• Captures data across three standardized exercise intensities (40%, 60%, and 75%–80% HRR), enabling intensity-specific comparisons.
• Integrates multiple data domains: anthropometry, body composition, cardiorespiratory fitness, and several psychological questionnaires.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect bias inherent to the specific study population of young adults (18–35 years).
